Earlier this month, we discussed what commercial roofing is, giving a quick glimpse into the materiality and maintenance required. Today we’re going to take the subject one step further, focusing on the types of commercial roofs available so that you can decide which system will work best for you. Some options are durable but expensive, while others are affordable and require more maintenance. So whether you’re building a new commercial space or replacing your current roof, read on to learn more about the different types of commercial roofs.
Types of Commercial Roofs
Thermoplastic polyolefin (TPO) roofs, although one of the newest types of commercial roofs on the market, are becoming more popular all the time due to their affordability and durability. They are lightweight and can be installed quickly, but they offer heavy-duty protection. Flexible and thermoplastic, they can be heat-welded when installed, creating incredibly strong seams. They are very resistant to UV, ozone, and chemical exposure, and they can also resist fire, punctures, and high winds. Expect TPO roofs to last for 20 years or more.
Versatile and strong, ethylene propylene diene monomer (EPDM) roofs are exceptionally long-lasting (40-50 years). These rubber polymer roofs resist UV rays, heat, and bad weather, and they offer low-temperature flexibility. Another popular choice for commercial roofs these days, EPDM roofs are also easy to install, maintain, and repair. Plus, since they’ve been trusted for over 40 years, you know you can count on them to really last.
A ballast roofing system utilizes gravel or pavers to weigh down roofing components (like the waterproof membrane, insulation, and vapor barrier). Used since the early 1970s, ballast is a time-tested technique that uses about 10-25 pounds of stones per square foot. None of the components are fastened together (though the membrane seams are sealed and the waterproof layer is secured to the parapet). They are simply “loose-laid,” but that doesn’t mean that they aren’t strong—they protect the roof from UV rays, hail, and foot traffic. Plus, they’re inexpensive, easy to install and maintain, and accommodate building movement.
Metal roofs are another strong, weather-resistant choice. Comprised of aluminum panels with Kynar coating, they can withstand wind, fire, and hail for up to 50 years or more. Plus, they’ve been around such a long time that there have been great advances in the metal alloys and coatings used, making them exceedingly tough. Metal roofing systems are only available for pitched roofs.
Green Roofing Options
If you’re looking for some types of commercial roofs that are eco-friendly and sustainable, try photovoltaic panels or sedum green roofs. PV solar panels can be installed over an existing rooftop or used in combination with glass, membrane, or roof-mounted tile. The solar panels absorb sunlight and convert it into energy that can be used to help power the building, lowering your current utility bills. Sedum green roofs, on the other hand, are covered in vegetation and soil. Planted over a waterproof membrane, your rooftop garden will soak up heat and water, and it will lower your heating/cooling costs. It can really improve your building’s insulation. Neither of these green types of commercial roofs are very popular right now, but they’re gaining momentum.
